Leners 'Patent No. 92,760, man .my 2o, 1869.

ORG'IAN-ACTION.

The Schedule referred to in these Letters Patent and makingpart of thesame.

To all whom it may concer-n:

Be it known that I, ADAM SToRcK, of Cincinnati, in the county ofHamilton, and State of Ohio, have invented a new and useful Improvementin Melodeon and Organ-Action; and I do hereby declare that the followingis a full, clear, and exact description thereof,

which will enable others skilled in the art to make and use the same,reference being had to .the accompanying drawing, forming part lof thisspecification, in.4

which--A Figure 1 represents a plan or proved melodeon or organ action.A

Figure 2 is a vertical transverse section of the same, taken on theplane of the line :1J-x, iig. 1.

Figure 3 isja vertical longitudinal section of the same, taken on theplane of the line y-ql, iig. 1.

' Similar letters of reference indicate corresponding top view of myimparts. l

with the. key.

The cams on the shaft are so placed that they will, for a desired key,majorer minor, throw the requisite reeds into gear.

There are twelve keys provided on the finger-boardl for each' octave,they being apted to the ordinary notes of the chromatic scale. Theenharmonic scale has, however, almost twice as many notes, which can, onthe ordinary action, n'ot be produced.v

The` object of this invention is,`therefore, to give to each key of thefinger-boardsnch a connection that it can play one of two notes, as maybe desired.

The invention will be readily understood from the following description,and from the drawing:

A, in the drawing, represents the frame of ,a' melodeou provided with myimproved -action.`

B B are the keys, pivoted to the frame, they being arranged asusual-twelve to each octave, as shown. l From the under side of eachkey, B, projects, downward, an arm, C, which is drawn forward-by aspring, a, to keep its key in a horizontal position.

Each arm C has a block, b, at its inner side, by

whichthe valve-rod pertaining to it is struck.

'Ihere are tw'o rows, I) and E, of reeds, one row in front oi`- theother, each row having as many reedsea's" there are keys B. There arcthustwo reeds for each key B.

rIhc reeds in theback row, E, reach lower than those of the front row,D, so that the valves in the former are alsosome distance lower thanthose in the latter.

F F are the valve-rods of the. front reeds, D, and G, those of the backreeds, E.

These rods are all tted through frames H, of which there are as many asthere are keys 'B.

Each frame H consists of two bars, c and d, pivoted together so as toform nearly a right angle.

The horizontal bar c is in line with the key to which i pertains,pivoted to the frame A, while the vertical bar d is suspended from thefront end of c, and reaches' down through' a cross-bar, e, of the frame.

The valve-,rods F G,which pertain to one set of reeds, are fittedthrough the vertical arm d,V of the frame H, and are supported by thesame.

The horizontal bar c, f each flame H, rests upon a roller, I, which.hasits bearings in the ends of the frame A, and which has a. series ofcams, f j, one be' low each bar b.

These cams are so disposed that, by turning the roller I, some frames'are raised on them, while other frames are left to rest on the surfaceof the roller.

When a frame,.H, is raised by means of a cam, j,

it-will carry the end of .its lower valverod, G, opposite the block, b,to bring thereby the back reed in connection with the key B, while thoseframesH which are not' raised hold the ends of theupper rods, F,opposite to the blocksb, to keep the front reeds in connection withtheir keys B.

The reedsin the back row, E, are for the next lower tones than those inthe front row,- as indicated in fig.

l, where, for eiample,`the rst front reed is for the note O, that behindit being for Bit. The next front reed is for Db and that in its rear forGili, and so on.'

1t is well known, that' in vthe enharmonic scale, Aa difference existsbetween thesha'rp of one note and the dat of the next following note.

On the shaft or roller I is mounted a disk, J, which has itscircumference` divided into twelve spaces, for the twelve mai'u keys.

. When the roller is turned, to bring the requisite one of its twelvespaces into a particular desired position, say to the front or top ofthe roller, the frames H will, by the camsj, have been acted upon, tobring those of the front and rear reeds into connection with the actionthat are needed for the requisite key.

K is a loose ring, tted around the rollerI, and convinected, by a strap,L, with a treadle, and held in position by a spring, g, by which it isconnected with the frame A, so 4that a stop, m, on the ring may strikea' fixed stop, fn.

A lug, h, is formed on the ring K, it fitting between one of twelverecesses ornotches formed on an annular plate, M, as shown.

The plate M is, by means of springsrods i i, connected with the rollerI, so that it is, by said springs,

held against the ring K, while it may be forced toward the disk J, toliberate the tooth h.

A suitable mechanism is provided to turn the shaft for each key.

I propose to arrange twelve stops in the middle of the instrument, onefor each key of tune, so that by pulling such key, the roller will beturned far enough to bring the requisite reeds into gear.

The thirds, fourths, &c., and all variations of a main key, can, by aslight motion of the treadle, be produced as long as needed, the springg carrying the roller back for the main key as soon as the treadle isreleased.

Having thus described my invention,

'What I claim as new, and desire to secure by4 Letters Patent, is-

l. A melodeon or organ-action, provided with two reeds or pipes for eachkey, and separate connections, F G, so adjustable that either one ofthem may be acted on bythe keyto which. they belong, substantjally asandfor the purposes set forth.

2. The cam-cylinder I f, constructed and operating in combination withthe frames H, substantially as described, for the purpose stated.

3. The frames H, employed to hold the valverods F G, of two sets ofreeds, in the requisite positions, and bring either one -into connectionwith its key B, as described, by the action of a cam -cylinder, I, orany other suitable mechanism.

4'. The combination of the ring K, sprinfr g, and treadlc, with the ringM, springs li, and disk of the roller I, all arranged and operatingsubstantially as herein shown and described.

5. 'The valve-rods F and G, of an organ or melodeonaction, whensupported, in pairs, by adjustable frames, substantially as herein shownand described, for thc purpose speciiied.
